Arch Linux Security Advisory ASA-201907-3
=========================================
Severity: High
Date : 2019-07-06
CVE-ID : CVE-2019-12781
Package : python2-django
Type : silent downgrade
Remote : Yes
Link : https://security.archlinux.org/AVG-1001
Summary
=======
The package python2-django before version 1.11.22-1 is vulnerable to
silent downgrade.
Resolution
==========
Upgrade to 1.11.22-1.
# pacman -Syu "python2-django>=1.11.22-1"
The problem has been fixed upstream in version 1.11.22.
Workaround
==========
None.
Description
===========
An HTTP request is not redirected to HTTPS when the
SECURE_PROXY_SSL_HEADER and SECURE_SSL_REDIRECT settings are used, and
the proxy connects to Django via HTTPS. In other words,
django.http.HttpRequest.scheme has incorrect behavior when a client
uses HTTP.
Impact
======
A remote attacker is able to perform a man-in-the-middle attack if a
HTTP request is not redirected to HTTPS.
